e283e77424 hv: vmcs: fix MISRA-C violations related to multiple exits
This patch fixes the MISRA-C violations in arch/x86/vmcs.c.
 * make the function have only one exit point

v1 -> v2:
 * update 'is_cr0_write_valid' and 'is_cr4_write_valid'
   use `if ... else` rather than check 'ret' value

36863a0b54 modulization: vmx on/off should not use vcpu param
vmx.c should only take care host vmx operations, which should not
contain vcpu reference, so refine vmx on/off APIs, move out use
of vcpu by adding one per cpu vmcs_run pointer.

as now each pcpu only run on one vcpu, so just keep running vmcs
in per cpu vmcs_run pointer is enough.

731c4836dd modulization: separate vmx.c into two parts
one part is pure vmx operations which keeps in vmx.c
the other part is vmcs operations which is vcpu related, move them
